The Middleton Railway is the world's oldest continuously working railway, situated in Leeds, West Yorkshire, England. It was founded in 1758 and is now a heritage railway, run by volunteers from The Middleton Railway Trust Ltd. since 1960.
Originally built under an act of Parliament, the Oystermouth Railway or Tramroad Act 1804, to move limestone from the quarries of Mumbles to Swansea and to the markets beyond, it carried the world's first fare-paying railway passengers under an agreement effective from 25 March 1807
